- the invention relates to a scaffold stand which consists of frame cross members dowelled with the uprights, in particular a straightening machine for sheets, strips and profiles with staggered upper and lower straightening rollers, which are supported over their length by means of support rollers which are in turn supported on cross members and arranged in roller mills. wherein at least the upper crossbar can be adjusted to position the straightening rollers.
- Multi-part scaffold stands which consist of uprights and between these cross beams used above and below, are known, for example, both for leveling machines and for rolling mill systems of all types and presses.
- Two scaffold stands opposite each other, forming a scaffold are connected to one another via an upper and a lower crossbar.
- the crossheads can be adjusted up and down by means of four adjusting cylinders, on the one hand to adapt the straightening gap to different thicknesses of the goods to be straightened and on the other hand to be able to influence the relative position of the upper and lower, mutually offset straightening rollers transversely to the direction of advance of the straightening goods.
- Adjustment devices are also available for the roll stands, with which the rolls can be adjusted or adjusted according to the strip or sheet thickness to be rolled.
- the invention is therefore based on the object of designing a generic scaffold stand, in particular a straightening machine for sheets and strips, in such a way that the disadvantages mentioned can be avoided and uniform load distribution can be achieved by means of stator connections which can be produced with little production outlay.
- the inner bore of the hollow bolt located in the region of the greatest sparing force is largest and the inner bore of the hollow bolt located in the region of the lowest sparing force is smallest. Due to the coordinated inner bores, the desired good force distribution on the individual hollow bolts can be supported or achieved.
- screw connections are introduced from the side into the uprights and the crossbeams. With these heavy screw or cross connections, the spreading forces occurring between the uprights and the frame crossbars can be absorbed. Hydraulic clamping devices, for example, are suitable for fastening the screw connections. Since the hollow bolt arrangements with the mutually coordinated inner bores enable uniform force distribution and thus hollow bolts with the same load bearing capacity, all screws can be dimensioned to be of the same size, so that the same screwing forces are present everywhere.
- a method for producing the dowel holes in a scaffold stand provides for simultaneous drilling of the bore holes required for the hollow bolts in the uprights and the frame cross members.
- the drilling together of the possibly pre-milled bore holes makes it possible for the hollow bolts to be inserted therein to have exactly the same pitch, ie the same distances between the hollow bolts.

- Roller setting wedges 8 are mounted on the lower roller mill 7, which are each displaceable by a pressure cylinder 9.
- a bearing carrier wedge 11 for lower straightening rollers 12 and support rollers 13 associated therewith is supported on each wedge 8; webs 14 are arranged between the support rollers 13.

Abstract
Description
Die Erfindung betrifft einen Gerüstständer, der aus mit den Ständerholmen verdübelten Rahmentraversen besteht, insbesondere einer Richtmaschine für Bleche, Bänder und Profile mit versetzt zueinander angeordneten oberen und unteren Richtwalzen, die über ihre Länge mittels ihrerseits an Quertraversen abgestützten, in Walzenstühlen angeordneten Stützrollen abgestützt sind, wobei zumindest die obere Quertraverse zur Positionierung der Richtwalzen anstellbar ist.The invention relates to a scaffold stand which consists of frame cross members dowelled with the uprights, in particular a straightening machine for sheets, strips and profiles with staggered upper and lower straightening rollers, which are supported over their length by means of support rollers which are in turn supported on cross members and arranged in roller mills. wherein at least the upper crossbar can be adjusted to position the straightening rollers.
Mehrteilige Gerüstständer, die aus Ständerholmen und zwischen diesen oben und unten eingesetzten Rahmentraversen bestehen, sind bspw. sowohl für Richtmaschinen als auch für Walzwerksanlagen aller Art und Pressen bekannt. Zwei einander gegenüberliegende, ein Gerüst bildende Gerüstständer sind über eine obere und eine untere Quertraverse miteinander verbunden. Bei bekannten Richtmaschinen sind die Querhäupter durch vier Anstellzylinder auf und ab anstellbar, um einerseits den Richtspalt an unterschiedliche Dicken des zu richtenden Gutes anpassen und andererseits die Relativlage der oberen und unteren, zueinander versetzten Richtwalzen quer zur Vorschubrichtung des Richtgutes beeinflussen zu können. Auch bei den Walzgerüsten sind Anstellvorrichtungen vorhanden, mit denen sich die Walzen entsprechend der jeweils zu walzenden Band- oder Blechdicke ein- oder nachstellen lassen.Multi-part scaffold stands, which consist of uprights and between these cross beams used above and below, are known, for example, both for leveling machines and for rolling mill systems of all types and presses. Two scaffold stands opposite each other, forming a scaffold, are connected to one another via an upper and a lower crossbar. In known straightening machines, the crossheads can be adjusted up and down by means of four adjusting cylinders, on the one hand to adapt the straightening gap to different thicknesses of the goods to be straightened and on the other hand to be able to influence the relative position of the upper and lower, mutually offset straightening rollers transversely to the direction of advance of the straightening goods. Adjustment devices are also available for the roll stands, with which the rolls can be adjusted or adjusted according to the strip or sheet thickness to be rolled.
Zum Verbinden der Ständerholme mit den Rahmentraversen ist es bekannt, Nuten vorzusehen und zur Verbindung Paßfedern einzusetzen. Um die beim Richten, Pressen oder Walzen auftretenden, erheblichen Kräfte aufnehmen zu können, ist allerdings mehr als eine Paßfederverbindung erforderlich. Denn bei lediglich einer Paßfedernut müßte diese sehr tief in die Ständerholme eingearbeitet werden, was eine außerordentliche Schwächung des Gerüstständers bedeutete. Es wurden deshalb mehrere Paßfederverbindungen angeordnet, wobei sich jedoch aufgrund der Mehrflächigkeit eine gleichmäßige Lastverteilung als außerordentlich problematisch herausgestellt hat, das heißt die auftretenden Kräfte lassen sich nicht über längere Strecken mit gleichtragenden Anteilen der einzelnen Paßfederverbindungen verteilen. Bedingt durch die Paßfedernuten und die darin eingesetzten Keile bzw. Paßfedern stellt sich außerdem eine sehr nachteilige Kerbwirkung ein.To connect the uprights to the frame cross members, it is known to provide grooves and to use feather keys for the connection. In order to be able to absorb the considerable forces that occur during straightening, pressing or rolling, however, more than one key connection is required. Because if there was only one feather keyway, it would have to be worked very deep into the uprights, which meant an extraordinary weakening of the scaffold stand. It was because of that Several feather key connections arranged, but due to the multi-surface, a uniform load distribution has proven to be extremely problematic, that is, the forces occurring can not be distributed over longer distances with identical portions of the individual feather key connections. Due to the feather keyways and the wedges or feather keys used therein, there is also a very disadvantageous notch effect.
Bei einem durch die GB-A-2 146 102 bekanntgewordenen Maschinenrahmen für beispielsweise Druckmaschinen werden bei der Montage die Wandteile des Maschinenrahmens nach Art von Dübeln durch Paßstifte und unterstützende Schraubbolzen miteinander verbunden. Allerdings bereitet auch diese Verbindung Probleme, wenn es darum geht, eine gleichmäßige Lastverteilung zu erzielen.In the case of a machine frame, known for example from GB-A-2 146 102, for, for example, printing presses, the wall parts of the machine frame are connected to one another in the manner of dowels by means of dowel pins and supporting bolts. However, this connection also causes problems when it comes to achieving an even load distribution.
Der Erfindung liegt daher die Aufgabe zugrunde, einen gattungsgemäßen Gerüstständer, insbesondere einer Richtmaschine für Bleche und Bänder so auszugestalten, daß sich die genannten Nachteile vermeiden und eine gleichmäßige Lastverteilung über mit geringem Fertigungsaufwand herzustellende Ständerverbindungen erreichen läßt.The invention is therefore based on the object of designing a generic scaffold stand, in particular a straightening machine for sheets and strips, in such a way that the disadvantages mentioned can be avoided and uniform load distribution can be achieved by means of stator connections which can be produced with little production outlay.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Rahmentraversen und die Ständerholme durch Hohlbolzen miteinander verdübelt sind. Mit der Erfindung lassen sich mehrere Vorteile gleichzeitig erreichen, nämlich die bei einer Bolzenverbindung wohl geringste Kerbwirkung ausschöpfen und gleichzeitig ausnutzen, daß die Hohlbolzen beim Auftreten von Last in eine ovale Querschnittsform zusammengedrückt werden und somit ausweichen können. Es läßt sich damit ein Verformungsweg erzielen, der dazu beiträgt, daß andere Stellen, nämlich die einzelnen Hohlbolzen, gleichmäßiger zum Tragen kommen. Wenn vorzugsweise in der Verbindungsfuge zwischen den Rahmentraversen und den Ständerholmen im Abstand übereinander mindestens zwei Hohlbolzen angeordnet und mit im Durchmesser unterschiedlich großen Innenbohrungen versehen sind, läßt sich das gleichmäßige Verteilen der Last auf alle Verbindungsstellen optimieren und so beeinflussen, daß die Tragfähigkeit bei allen Hohlbolzen gleich wird. Gleichwohl läßt sich durch entsprechende Wahl der Innenbohrungen der Hohlbolzen auch eine gleiche Lastverteilung auf die einzelnen Hohlbolzen erreichen, falls das vom Anforderungsprofil her erwünscht wird.This object is achieved in that the frame cross members and the uprights are pegged together by hollow bolts. With the invention, several advantages can be achieved at the same time, namely exploiting the slightest notch effect with a bolt connection and at the same time taking advantage of the fact that the hollow bolts are compressed into an oval cross-sectional shape when load occurs and can thus deflect. A deformation path can thereby be achieved which contributes to the fact that other points, namely the individual hollow bolts, come to bear more evenly. If preferably at least two hollow bolts are arranged at a distance above one another in the connecting joint between the frame crossbars and the uprights and are provided with inner bores of different sizes, the uniform distribution of the load over all connecting points can be optimized and so influence that the load capacity is the same for all hollow bolts. Nevertheless, by appropriate selection of the inner bores of the hollow bolts, an equal load distribution over the individual hollow bolts can also be achieved, if this is desired from the requirement profile.
Nach einer vorteilhaften Ausgestaltung der Erfindung wird vorgeschlagen, daß bei drei übereinander angeordneten Hohlbolzen die Innenbohrung des sich im Bereich der größten Holmkraft befindenden Hohlbolzens am größten und die Innenbohrung des sich im Bereich der kleinsten Holmkraft befindenden Hohlbolzens am kleinsten ist. Aufgrund der somit abgestimmten Innenbohrungen läßt sich die gewünscht gute Kraftverteilung an den einzelnen Hohlbolzen unterstützen bzw. erzielen.According to an advantageous embodiment of the invention, it is proposed that with three hollow bolts arranged one above the other, the inner bore of the hollow bolt located in the region of the greatest sparing force is largest and the inner bore of the hollow bolt located in the region of the lowest sparing force is smallest. Due to the coordinated inner bores, the desired good force distribution on the individual hollow bolts can be supported or achieved.
Es wird erfindungsgemäß vorgeschlagen, daß von der Seite her in die Ständerholme und die Quertraversen Schraubverbindungen eingebracht sind. Mit diesen schweren Schraub- bzw. Querverbindungen lassen sich die zwischen den Ständerholmen und den Rahmentraversen auftretenden Spreizkräfte aufnehmen. Zur Befestigung der Schraubverbindungen eignen sich bspw. hydraulische Spannvorrichtungen. Da die Hohlbolzenanordnungen mit den aufeinander abgestimmten Innenbohrungen eine gleichmäßige Kraftverteilung und somit gleichtragende Hohlbolzen ermöglicht, lassen sich alle Schrauben gleich groß dimensionieren, so daß überall gleiche Schraubkräfte vorliegen.It is proposed according to the invention that screw connections are introduced from the side into the uprights and the crossbeams. With these heavy screw or cross connections, the spreading forces occurring between the uprights and the frame crossbars can be absorbed. Hydraulic clamping devices, for example, are suitable for fastening the screw connections. Since the hollow bolt arrangements with the mutually coordinated inner bores enable uniform force distribution and thus hollow bolts with the same load bearing capacity, all screws can be dimensioned to be of the same size, so that the same screwing forces are present everywhere.
Ein Verfahren zur Herstellung der Dübellöcher in einem Gerüstständer sieht erfindungsgemäß ein gleichzeitiges Aufbohren der für die Hohlbolzen in den Ständerholmen und den Rahmentraversen benötigten Bohrungslöcher vor. Das gemeinsame Aufbohren der gegebenenfalls vorgefrästen Bohrungslöcher ermöglicht es, daß sich für die darin einzusetzenden Hohlbolzen eine exakt gleiche Teilung, d.h. gleiche Abstände der Hohlbolzen voneinander erreichen lassen.According to the invention, a method for producing the dowel holes in a scaffold stand provides for simultaneous drilling of the bore holes required for the hollow bolts in the uprights and the frame cross members. The drilling together of the possibly pre-milled bore holes makes it possible for the hollow bolts to be inserted therein to have exactly the same pitch, ie the same distances between the hollow bolts.

Die erfindungsgemäße Ständerverbindung wird anhand einer in den Zeichnungen dargestellten Rollenrichtmaschine 1 beschrieben. Bei der Rollenrichtmaschine 1 wird der Maschinenrahmen durch zwei am Fundament verankerte Ständer 2, 3 gebildet, die durch eine obere Rahmentraverse 4a - eine untere Rahmentraverse ist nicht dargestellt- sowie eine untere und obere Quertraverse 4, 5 starr verbunden sind. An der oberen Quertraverse 4 ist ein oberer Walzenstuhl 6 gehalten; ein unterer Walzenstuhl 7 ist verfahrbar auf der unteren Quertraverse 5 angeordnet. Die obere Quertraverse ist über Anstellzylinder 10 gegen die untere Quertraverse 5 anstellbar; jeweils ein- und auslaufseitig an den Ecken angeordnete und somit insgesamt vier Anstellzylinder 10 greifen an die obere Quertraverse 4 an.The stator connection according to the invention is described with reference to a roller straightening machine 1 shown in the drawings. In the roller straightening machine 1, the machine frame is formed by two
Auf dem unteren Walzenstuhl 7 sind Rollenanstellkeile 8 gelagert, die durch je einen Druckmittelzylinder 9 verschiebbar sind. Auf jedem Anstellkeil 8 ist ein Lagerträgerkeil 11 für untere Richtrollen 12 und diesen zugeordneten Stützrollen 13 abgestützt; zwischen den Stützrollen 13 sind jeweils Stege 14 angeordnet. Weiterhin sind mehrere obere Richtrollen 15 an ihren Ballen abgestützt, und zwar mittels Stützrollen 17, die sich zwischen Stegen 16 befinden. Die oberen Richt- und Stützrollen 15, 17 sind an einem Lagerträgerkeil 18 gelagert. Jeder der benachbarten Lagerträgerkeile 18 ist an einen Anstellkeil 21 abgestützt, dessen andere Seite am oberen Walzenstuhl 6 anliegt. Die Anstellkeile 21 sind durch je einen Druckmittelzylinder 22 verschiebbar. Die oberen und unteren Richtrollen 5, 12 sind einzeln angetrieben und über Gelenkwellen 23 mit einem nicht dargestellten Antrieb verbunden.
Wie in den Fig. 2 und 3 gezeigt ist, sind die Ständerholme 2a, 3a der Ständer 2, 3 des Maschinenrahmens durch jeweils drei im gleichen Abstand übereinander in die Verbindungsfuge 24 zwischen den Rahmentraversen 4a und 5, wobei die letztere, untere Rahmentraverse identisch mit der Quertraverse ist, eingesetzte Hohlbolzen 25, 26, 27 verbunden. Um die beim Betrieb auftretenden Spreizkräfte aufnehmen zu können, sind die Ständerholme 2a, 3a und die Rahmen- bzw. Quertraverse 4a, 5 außerdem durch von den außen liegenden Seiten der Ständerholme 2a, 3a eingeschraubte Schrauben 28 miteinander verbunden.As shown in FIGS. 2 and 3, the
Wie sich näher aus Fig. 4 ergibt, sind die Hohlbolzen 25 bis 27 mit im Durchmesser unterschiedlichen, aufeinander abgestimmten Innenbohrungen 29 bis 31 versehen, und zwar weist der im Bereich der größten Holmkraft angeordnete Hohlbolzen 25 die Innenbohrung 29 mit dem größten und der im Bereich der kleinsten Holmkraft angeordnete Hohlbolzen 27 die Innenbohrung 31 mit dem kleinsten Durchmesser auf. Auf diese Weise läßt sich eine gleichmäßige Kraftverteilung mit einer bei allen Hohlbolzen 25 bis 27 gleichen Tragfähigkeit erreichen. Denn beim Auftreten der von den Ständern 2, 3 aufzunehmenden Kräfte bewirken die unterschiedlichen Durchmesser der Innenbohrungen 29 bis 31 entsprechend unterschiedliche Ovalisierungen der Querschnitte der einzelnen Hohlbolzen, wodurch die Lastverteilung beeinflußt wird. Zudem entsteht wegen der geringen Kerbwirkung der Hohlbolzen 25 bis 27 eine sehr kompakte Verbindung.As can be seen in more detail from FIG. 4, the
